Damn! I will try and work something else out. I will leave the response I got from Bubble support below for everyone else.

Hello,

Thanks for reaching out! If you’re worried about someone figuring out who a report was created by in the Bubble database, you can set privacy rules to ensure that a user cannot see the email address associated with a report unless they are authorized to do so. Unfortunately, there is no way to encrypt a user’s email address within the datatable for Bubble itself, so if your concern is that your user is able to access the data fields in the application’s editor, that is not something that can be resolved.
